What happens to your DST file
A common route from a digitiser to a Janome machine. JEF needs a thread for each stop and picks the closest in the Janome list, so set your colours first. Also note that JEF has no trim record: the machine works out where to cut from jump length, so a short jump that was a cut in the DST may stay uncut.
| Stitch positions | Identical, to 0.1 mm |
|---|---|
| Colour stops | Same number, same order |
| Thread colours | Choose them first |
| Size and density | Unchanged |
Thread colours
DST stores no colours, and JEF needs one for each stop. Hoopbench starts with stand-in colours, so set your own under Colour stops before you download. Each becomes the nearest thread in the Janome chart.
Long moves
JEF can move 12.7 mm in one record and DST only 12.1 mm, so everything fits. Chains of jumps from the DST file stay as jumps.
Trims
JEF has no trim record. Trims are dropped from the file and the machine cuts when a jump is long enough, usually about 3 mm or more.
Before you stitch
- Open the .dst file above and watch it sew, so you know the file is sound and in the order you expect.
- Choose your hoop under Hoop fit. The check uses the design's real size, not the file's header.
- Pick your thread colours under Colour stops, because DST doesn't hold them.
- Download the .jef file, and stitch a test piece on matching fabric and stabiliser.
Converting doesn't resize a design or change its density. If a design needs to be much bigger or smaller, use digitising software, as stretching stitches without recalculating them can leave gaps or heavy spots.
About DST
DST is the file most digitisers deliver, because almost every commercial machine can sew it. It starts with a 512 byte text header holding the design name, stitch count and extents, followed by three bytes for every stitch.
Thread colours and thread names. A DST only says "stop and change thread here".
About JEF
JEF is the Janome format. Its header records the hoop it expects, the stitch count, and a colour for each stop as a slot in a fixed Janome thread list.
The JEF file is for Janome machines, and Elna machines that read JEF. Any Janome or Elna machine that reads JEF.
If you need a cut after a very short jump, a JEF machine may not make it. Inspect the jumps before you run it.
